Synthesis and Characterization of BaTiO₃-(Bi_0.5Na_0.5)TiO₃ Solid Solution Based Dielectric Ceramics

Abstract:

BaTiO₃-(Bi_0.5Na_0.5)TiO₃ (BTBNT) solid solution ceramics with the Curie temperature higher than 150°C were prepared, which were promising for X9R MLCCs application. (Bi0.5Na0.5)TiO3 (BNT) was first synthesized by the conventional solid state reaction and then it was mixed with BaTiO₃ (BT) with increasing BNT content from 0 to 12 mol%. BaTiO₃-(Bi_0.5Na_0.5TiO₃ solid solutions were obtained after calcining at 1100°C. The structural and dielectric properties of BTBNT and Nb-doped BTBNT ceramics were investigated.
